JOINT-FASTENER- Specification of Letters Patent.

Patented July 17, 1906.

Application filed J U118 24. 1905- SariaI No. 266,752-

To all whom it may concern:

Be it known that I, JOSEPH A. STEINMETZ, a'citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Im rovements in J oint-Fasteners of which the fdllowing is a specification.

This invention is designed to provide simple and inexpensive means for efiectivelyolding together abutting members, such as sections of wood conduits. timber ends, floor-boards, deck-planks, and the like. In the accompanying drawin s, Figure 1 represents a perspective view 0 the mvention, and Fig. 2 represents a sectional view thereof in it's operative relation to two abuttin members.

he device consists, essentially, of sheet metal having tines struck from the metal thereof and projecting in opposite directions therefrom.

As shown in the drawings, it consists, preferably, of the body portion 1, havin the oppositel -extending tines 2 on parallel edges thereo and the oppositely-extending tines3 projecting from t e interior of the body, the tines bein struck out of metal forming the bod and ent at right angles thereto.

T e edge tines are preferably made lon er than the bod -tinesand may be provi edwith the crimps 2 to stifien them, so that they of a body will resist the tendency to bend under transverse stress while being forced into the abuttin members 4.

asteners of this character can be struck out of sheet metal very readily and without waste of material, providing effective means together abutting wood members for oining of various kinds.

While it is preferred to formthe device by striking the same out of sheet metal, it ma be formed by casting a body or plate with tines projecting from opposite faces thereof.

Having described my invention, I claim 1. A j oint-fastener comprising a sheetmetal body with tines formed from the metal extendin in opposite directions and disposed along an withm edges, the edge tines being tapered and extending alternatelyin opposite directions.

2. A joint-fastener comprising a sheetmetal body with tapered tines formed from the metal, extending in oplplosite directions, and disposed along and wit 'n the edges, the edge tines being crlmped and of greater length 5 5 than the interior tines.

In testimony whereof I have hereunto set my name this 23d day of June, 1905.
